Offers made to the Palestinian delegation in Cairo where negotiations for a truce with Israel are being brokered do not meet the aspirations of the Palestinian people, Hamas's head of foreign affairs, Osama Hamdan, said.

Hamdan said on his official Facebook page on Saturday that "Israel must accept the demands of the Palestinian people or face a long war."

Israel and the Palestinians agreed on Wednesday to extend a ceasefire agreement in Gaza by five days to continue negotiations on a lasting truce. The ceasefire expires on Monday.
